Transmitters with displays offer a larger number of programming and processing op-
tions. These options include alarm status, damping, signal inversion, tank lineariza-
tion and diagnostic messages.
5.2 Function
The pressure transducer converts the existing pressure into an electrical signal. Mi-
croelectronics further process the input signal and produce a proportional 4-20 mA
standard signal.
The display-version allows programming (parameterization) and the display of ex-
tended functions such as inversion, damping, alarm status and linearization.
5.2.1 Functions of Transmitters without Displays
• Calibration of zero and span under pressure (see 8.3)
• Calibration of zero and span without pressure (dry adjustment) (see 8.4)
• Setting the dampening / integration of the output signal 0-40 s (see 8.5)
• Reset to manufacturer’s default values (see 8.6)
• Mounting correction of the sensor (beginning with software version 1.05, see 8.4.3)
5.2.2 Functions of Transmitters with Displays
• Settable units of measurement (mbar, bar, psi, mA, %, m, mm WS) (see 9.5.1)
• Volume-related unit of measuring value can be set (l, kg, t, m
3
, gal, lb) (see 9.5.1)
• Temperature and Min/Max values shown in display (see 9.5.1)
• Nominal pressure range of the sensor shown in display (see 9.5.1)
• Zero and span calibration (with/without pressure) (see 9.5.2)
• Setting of damping / integration of output signal 0-40 s (see 9.5.3)
• Inversion of the output current signal (see 9.5.3)
• Setting the output current value in case of alarm (3.6 mA or 21 mA) (see 9.5.3)
• Setting the limits of the output signal (see 9.5.3)
• Offset of the output signal (see 9.5.3)
• Mounting correction of the sensor (beginning with software version 1.05, see 8.4.3)
• Measuring circuit test function (see 9.5.4)
• Reset functions (see 9.5.4)
• Password activation (see 9.5.4)
• Selecting the language of the display (see 9.5.5)
• Entering of a table function for the linearization of the output signal (see 9.5.6)
• Entering the medium density (see 9.5.6)
Display units can be easily upgraded (see chapter 7.2).
